Add Attachments to Invoices
You can add an attachment, like a contract or images, directly to your Square Invoice, so your customer will have all of the purchase information in one place.
When creating an invoice, click Add Attachments to upload documents or images from your computer.
Note: Image files and PDFs can be uploaded with a combined file size limit of 25MB with a maximum of 10 files. You can upload file types PDF, PNG, and JPG.
Add additional attachments one at a time or remove uploaded attachments by clicking X.
Continue creating the invoice then Send or Schedule.
Before sending your invoice, select Preview in the top right-hand corner to view your invoice as your customer will see it. You can also click Save as draft to save the current version to work on later.
Do not use this feature to upload any Personal Health Information, illegal content, or content in violation of Square’s Terms of Service. Content you upload may be reviewed and used by Square in connection with contesting a chargeback.
